Michael Foods is a major egg supplier that serves some of the biggest names in the food business. The food industry heavyweight also carries the unfortunate distinction of confining millions of egglaying hens in some of the worst conditions in the egg industry—an industry already notorious for its disregard for animal welfare.

Last winter, an employee at a Michael Foods egg factory farm in Wakefield, Nebraska, documented the routine mistreatment of thousands of hens. The employee’s primary job was simple: remove dead birds. The employee pulled hundreds of corpses out of cages for eight hours every day.

The employee also carried a hidden video camera. The footage from the farm shows live hens caught in cage wires and confined in cages with dead birds; sick and injured hens; and hens dying from dehydration and starvation, just inches away from food and water.
